Phonak's Aud?o line of headphones has just been expanded to include a new interesting high-end in-ear dubbed the PFE232. PFE232 is a dual balanced armature based in-ear that aims at taking on the big guns in the high-end in-ear arena. We test them to see how they perform compared to in-ears like Westone 4 and the Ultimate Ears In-Ear Reference Monitors!
